非謂語動詞
【非謂語動詞】
構(gòu)成:(to)+動詞原形 動詞不定式
非 在句中的作用(除謂語動詞外的任何成分) 謂 構(gòu)成:V.-ing 語 動名詞

構(gòu)成:V. -ing / V.-ed(規(guī)則變化) 分詞
用法(表、補、定、狀)
(一)動名詞
一、動名詞的構(gòu)成:動名詞一般由“動詞原形+ing”構(gòu)成 二、動名詞的句法功能 功能 例句
說明
主語
Eating too much is bad for your health. 吃得太多對你的健康有害。
謂語動詞用單數(shù)形式。
賓語 動詞賓語
介詞賓語 I like playing basketball very much.我非常喜歡打籃球。
Stamps are used for sending letters.郵票是被用來寄信的。
表示一般的習慣或抽象行為或經(jīng)常性的動作。 表語 His hobby is collecting stamps. =Collecting stamps is his hobby. 多數(shù)情況下,動名詞作表語可轉(zhuǎn)化成作主語。
定語
She is in the reading room.她在閱覽室。
We should improve our teaching methods.我們應該改進教學方法。
只表明它所修飾的詞的用途、所屬關(guān)系等。置于所修飾詞之前。
注意:英語中有一些詞后面常跟動名詞作賓語。我們初中階段常見的有:finish, mind, be worth, be busy, practice, have fun, have trouble/problem(in), spend...(in), feel like, be used to(習慣于), give up, keep on, consider, suggest, can't help。我們可按下面的順口溜記憶這些詞。 完成實踐值得忙(finish, practice, be worth, be busy) 繼續(xù)習慣別放棄(keep on, be used to, give up)
考慮建議不禁想(consider, suggest, can't help, feel like) 喜歡思念要介意(enjoy, miss, mind)
(二)動詞不定式 一、動詞不定時的構(gòu)成
不定時的基本形式為:to+動詞原形,有時可以不用to,這里的to 是不定式符號,本身無詞義,動詞不定式的否定形式是not+(to+)動詞原形。
二、動詞不定式的句法功能 功能 例句 說明
主語
To speak English is not easy for us=It is not easy for us to speak English. 講英語對我們來說不容易。
作主語用的不定式,常常用it作形式主語,而把不定式放在后面。 表語 My work is to clean the room everyday.=To clean the room every day is my work. 我的工作就是每天打掃這間
屋子。
多數(shù)情況下,不定式作表語,可轉(zhuǎn)換作為
主語。
賓語 —What sports does he like to play?他喜歡做什么運動? —He likes to play basketball.他喜歡打籃球。 只能做某些動詞的賓語,一般不作介詞的賓語。
賓補
My mother made me play the piano all the time. 我媽媽讓我一直彈鋼琴。
在make,let,see,hear,watch等使役、感官動詞后,不定式省略to。
定語 Have you got anything to say? 你有要說的嗎?
不定式作定語,要放在所修飾詞的后面。 狀語 I'm sorry to trouble you.(表原因)很抱歉,給你添麻煩
了。
I went to the library to study English.(表目的)
不定式作狀語,其邏輯主語要和句子的主語一致。
1. 不定式作主語
動詞不定式作主語時,常用it作形式主語,而將真正的主語放在句末
其結(jié)構(gòu)為:It+be+adj.(+ for/ of sb.)+動詞不定式
如:To learn English well is useful.→ It is useful to learn English well. It’s important for us to protect the environment.
注意:在kind,good,nice,clever等表示人的品質(zhì)的形容詞后,不用for而用of。如: It's very kind of you to help me. 你幫助我真是太好啦。 It's very clever of you to do like that. 你那樣做真是太聰明啦。 2. 不定式作賓語
、 有些謂語動詞后只能用不定式作賓語,常見的這類詞是表示命令、打算或希望的,如: would like, like, want, wish, hope, decide, plan, expect等。如: Would you like to see a film this evening? 你今晚想去看電影嗎?
、谠趂ind, think后跟不定式作賓語時,常用it代替,而將真正的賓語放在后面。如: I find it easy to read English every day. ③常見的一些不帶to的動詞不定式
Why not do..., Why don't you do..., had better(not)do..., would rather do
could/would/will you please(not)do...
I would rather stay in the room.我寧愿待在房間里。 3. 不定式作賓語補足語
不定式作賓語補足語時與賓語有邏輯上的主謂關(guān)系。如: Lucy asked him to turn down the radio. 露西讓他關(guān)小收音機。
tell, ask, want, allow, get, would like, encourage后常跟動詞不定式作賓語補足語。如: My mother encourages me to learn Japanese. 我媽媽鼓勵我學日語。
注意:還有一些使役動詞和感官動詞也用不定式作賓補,這時不定式要省略to。這些動詞有:
一感(feel)、二聽(hear, listen to)、三讓(let, make, have)、四看(look at, see, watch, notice)。但變被動語態(tài)時,必須加上to。如:
My friends were made to work the whole night by the boss. 老板讓我的朋友們工作了一整夜。 4. 不定式作定語
、俨欢ㄊ阶鞫ㄕZ時,應放在名詞之后。它與名詞有邏輯上的動賓關(guān)系。
、谌绻遣患拔飫釉~,且與所修飾的詞之間有動賓關(guān)系,要在不定式后加上適當?shù)慕樵~。 There is nothing to worry about. 沒有什么可擔心的。
5.不定式常和疑問詞what, which, when, where, how連用,相當于一個賓語從句。如: The teacher is telling the students what to do. 老師正告訴學生們做什么。 He didn't know where to go. 他不知道去哪里。
非謂語動詞
定義:動詞除在句子中作謂語以外,還具有名詞、形容詞及副詞的性質(zhì),在句中可作主語、表語、賓語、定語、狀語和補語等,這就是動詞的非謂語動詞。可分為三種:動詞不定式、分詞和動名詞。
一.后面可跟動詞的ing形式的情況
1.動詞: finish doing sth.完成做某事;enjoy doing sth. 喜歡做某事;practice doing sth. 練習做某事;imagine doing,想象做某事;avoid doing sth.避免做某事;consider doing sth.考慮做某事;suggest doing sth.建議做某事;mind doing sth.介意做某事; keep doing sth.持續(xù)做某事 2.固定短語: feel like doing sth.喜歡做某事;be busy doing sth.忙于做某事;be worth doing 值得做某事;spend time (in) doing sth.花費時間(金錢)做某事; have difficult/trouble in doing sth做某事有困難;have fun doing.做某事高興
3.介詞后(on, in, of, about, at, with, without, for, from, up, by等)
如:be good at doing sth.;thank you for doing sth.;give up doing sth.;stop sb. from doing sth.;do well in doing sth.;be afraid of doing sth.;be interested in doing sth.;be proud of;instead of;be fond of
4.to作介詞的情況look forward to doing sth期望做某事; prefer doing sth. to doing sth與…相比較更喜歡…; pay attention to doing注意做某事; be/get used to doing sth.習慣于做某事;
二.后面可跟動詞的不定式形式的情況
1.動詞:agree to do同意去做;afford to do買得起;decide to do決定去做某事;hope to do希望去做;wish to do希望去做;fail to do做某事失敗去;plan to do打算去做;pretend to do假裝去做; refuse to do拒絕去做;would like to do想要去做;want to do想要去做某事;learn to do 學做;prefer to do sth. 喜歡(愛)做某事;sb. seem to do sth好像做某事;want/would like to do sth.
高中英語非謂語動詞教案2
在做單選題,如果遇到非謂語動詞,可以根據(jù)句中的搭配結(jié)構(gòu)、非謂語的主被動形式和非謂語的“時態(tài)”三個角度,從語言的結(jié)構(gòu)到語義由簡單到復雜依次排選。
第一步:根據(jù)非謂語形式在句中可作的成分來分析空白處可填入的非謂語形式,看能否在不定式、分詞和動名詞幾個形式之間先排除一個或幾個。
非謂語動詞在句中可作成分一覽表
主語賓語表語定語狀語賓補
不定式√√√√√√
分詞√√√√
動名詞√√√√
注:1).theÇ分詞也可用作主語和賓語;
2).現(xiàn)在分詞完成式不作定語。
1. 非謂語形式作主語或賓語時,除“theÇ分詞”外一般只能用不定式或動名詞。其中不定式作介詞的賓語時要使用“特殊疑問詞Ç不定式”結(jié)構(gòu)。
例如:1).It’s very kind of you to help us.
2).Fighting broke out between the South and the North.
3).The driver failed to see other cars at the moment .
4).Please show us how to do that.
2. 作狀語時,不定式表示目的以及so/as¼to do和(only)to do中的結(jié)果狀語,其它狀語都用分詞來表示。
例如:1).To sleep late the next morning,he turned off the alarm clock.
(“非謂語Ç主句”模式中,非謂語在句首而且由逗號與主句隔開,此句中的不定式只作目的狀語;此時的分詞表示時間、原因或條件狀語,有時分詞前可加when,while,if,before, after,as和though等連詞,如:①Given more attention,the trees could have grown better. ②When asked,never be silent.)
2).He came here only to say good-bye to us.
(不定式在句中作目的狀語時它前面不能用逗號)
3).He spoke a lot at the conference,only to show his ignorance on the topic.
(不定式在主句之后,又有逗號與主句隔開時常用(only)to do形式表示出乎主語意料的結(jié)果)
第二步:在第一步的基礎(chǔ)上從非謂語的主被動形式這個角度進行篩選。
1. 非謂語用作主語或狀語時,一般根據(jù)它們的邏輯主語來判斷主被動形式的選用;若無邏輯主語,則以主句主語為判斷對象。
例如:1).Using the dictionary,I found it of great use.
(作狀語的分詞邏輯主語和主句主語相同時,邏輯主語常省去)
2).It’s so nice to hear your voice.
3).Seeing is believing.
(不帶邏輯主語的不定式或動名詞作主語時,通?醋鞯谝蝗朔Q的邏輯主語省略)
注意以下特殊情況中非謂語一律用主動式:
①主語Ç系動詞Ç形容詞Ç不定式
、趎eed/want/require(需要) Çdoing
、踒e worth doing
2. 作賓語或表語時,要根據(jù)主句主語來分析主被動形式。
例如:1).The little girl would like to be brought to the State with her brother.
2).His story in the jungle is very exciting.
3. 作定語時,應根據(jù)被修飾詞來選用主被動形式。
例如:1).I have a room to paint,so I can’t go out for a picnic with them.
2).We have a room to be painted.Where can we find a worker?
(當句中出現(xiàn)了作定語的不定式動詞的執(zhí)行者時用主動式,否則用被動式)
4. 作賓補的非謂語主被動形式要根據(jù)非謂語動詞與賓語的關(guān)系來確定。
例如:1).Don’t have the water running like that.
2).She sat alone in the room,with her eyes fixed on the ceiling.
第三步:經(jīng)過第一、二兩步分析仍未能作出最后選擇時,可能會剩下不定式和分詞內(nèi)部不同的式之間的選擇,即非謂語的“時態(tài)”,這時可通過比較非謂語動詞和謂語動詞所發(fā)生的先后來判別。
1. 不定式的一般式to do/to be done常用在
、俦硎痉侵^語動詞發(fā)生在謂語之后;
例如:1).I hope to see you again soon.
2).Who do you think our teacher will have work on the wall-newspaper?
②表示與謂語動詞同時發(fā)生的一個全過程動作或謂語當時所處的狀態(tài)。
例如:4).Have you seen a little boy go into the house?
5).He seems to know that.
2.不定式的進行式to be doing 和現(xiàn)在分詞的一般式doing/being done只用來表示非謂語動詞和謂語動詞同時發(fā)生。
例如:1).The secretary worked late into the night, preparaing the long speech for the president.
2).They pretended to be sleeping when Mother came in.
3.不定式完成式to have done/to have been done和現(xiàn)在分詞完成式having done/having been done均表示動作發(fā)生在謂語之前。
例如:1).He is said to have left.
2).Not having heard from him,I wrote to him again.
4.詞常表示發(fā)生在謂語之前而及物動詞的過去分詞則可以指發(fā)生在謂語之前或與謂語同時的狀態(tài)。
例如:1).fallen leaves/a burnt-out match
2).The thief was brought in,with his hands tied behind.
若非謂語形式正確而詞義仍不同者則需從句義來考慮。
非謂語動詞的一般式表示的動作與謂語動詞表示的動作同時發(fā)生或在其后發(fā)生,非謂語動詞的完成式表示的動作發(fā)生在謂語動詞表示的動作之前。
1.動詞不定式
例1:A lot of young people are learning to drive cars. (同時發(fā)生)
例2:All of us expected to discover a new oil field. (非謂語動詞動作發(fā)生在后)
例3:He is said to have studied English for three years. (非謂語動詞動作發(fā)生在前)
注:動詞不定式的完成式有時用在intended, expected, meant, were to, was to等過去式的動詞后面,表示未實現(xiàn)的行為。例如:
1)I meant to have sent the book to you by mail. (我本想把這本書郵寄給你的。)
2)He was to have been the new ambassador, but he fell ill. (他原是要任新大使的,但是他病了。)
2.動名詞
例1:I am thinking of getting a new dictionary. (非謂語動詞動作發(fā)生在后)
例2:We enjoy watching colour TV. (與謂語動詞動作同時)
例3:He forgot having promised to write things for us. (非謂語動詞動作發(fā)生在前。)
3.分詞
例1:Singing a song, he came into the room. (非謂語動詞動作與謂語動詞動作同時發(fā)生)
例2:Having written his composition, he went to have a heart to heart talk with Wang. (非謂語動詞動作發(fā)生在前)
非謂語動詞的比較
1.動名詞和動詞不定式在用法上的比較
(1)一般說來動名詞所表示的動作在意義上是比較抽象的、一般的,時間概念不強,不是指某一次的動作;而動詞不定式所表示的動作則往往是具體的一次行為。例如:
1)I like swimming, but I don’t like to swim today.
2) They prefer staying indoors when the weather is cold.
3) Would you prefer to stay at home this evening?
(2)動詞不定式的邏輯主語,常常是句子的主語或句中的某個詞;而動名詞的邏輯主語可能是句子主語或句中某個詞,也可能是泛指一般人物,在句子里是找不著的。例如:
1)I hate to be sitting idle. (我不想閑坐著。)(指自己)
2)I hate saying nothing at a meeting but gossiping afterwards. (我不喜歡開會不說會后亂說。)(可能指自己,也可能泛指一般人)
(3)有些詞后既可接動名詞亦...

注意:疑問詞帶不定式在句中作成分時,謂語動詞用單數(shù)。
The question is how to put it into practice. 問題是怎樣把它付諸實施。
2 不定式作補語
1) 動詞+賓語+不定式(to do)
advise allow appoint believe cause challenge command compel consider declare drive enable encourage find forbid force guess hire imagine impel induce inform instruct invite judge know like order permit persuade remind report request require select send state suppose tell think train trust understand urge warn
a. Father will not allow us to play on the street. 父親不讓我們在街上玩耍。
b. We believe him to be guilty. 我們相信他是有罪的。
Find 的特殊用法:
Find 后可用分詞做賓補,或先加形式賓語,再加形容詞,最后加帶to 的動詞不定式。find后也可帶一個從句。此類動詞還有g(shù)et,have。
I found him lying on the ground. I found it important to learn.
I found that to learn English is important.
The next morning she found the man ___ in bed,dead. A. lying B. lie C. lay D. laying
答案:A.find的賓語后面,用分詞或分詞短語,起賓語補足語作用,F(xiàn)在分詞表達主動,也表達正在進行,過去分詞表達被動。
2) to + be 的不定式結(jié)構(gòu),作補語的動詞。
Acknowledge, believe, consider, think, declare(聲稱), discover, fancy(設(shè)想), feel find, guess, judge ,imagine, know, prove, see(理解), show ,suppose, take(以為), understand
We consider Tom to be one of the best students in our class.
我們認為湯姆是班上最好的學生之一。
Charles Babbage is generally considered ___ the first computer.
A. to invent B. inventing C. to have invented D. having invented
答案:A. 由consider to do sth. 排除B、D。. 此句只說明發(fā)明這一個事實,不定式后用原形即可。而C為現(xiàn)在完成時,發(fā)明為點動詞一般不用完成時,且此處也不強調(diào)對現(xiàn)在的影響,因此不選C。
3) to be +形容詞
Seem, appear, be said, be supposed, be believed, be thought, be known, be reported, hope, wish, desire, want, plan, expect, mean…
The book is believed to be uninteresting. 人們認為這本書沒什么意思。
4) there be+不定式

2) 不定式作為句子成分時,動詞用單數(shù)形式。
3) 當不定式作主語的句子中又有一個不定式作表語時,不能用It is… to…的句型
(對)To see is to believe. 百聞不如一見。
4 It's for sb.和 It's of sb.
1)for sb. 常用于表示事物的特征特點,表示客觀形式的形容詞,如easy, hard, difficult, interesting, impossible等:

2)of sb的句型一般用表示人物的性格,品德,表示主觀感情或態(tài)度的形容詞,如good, kind, nice, clever, foolish, right。
It's very nice of you to help me. 你來幫助我,你真是太好了。
for 與of 的辨別方法:
用介詞后面的代詞作主語,用介詞前邊的形容詞作表語,造個句子。如果道理上通順用of,不通則用for。如:
You are nice. (通順,所以應用of)。
He is hard. (人是困難的,不通,因此應用for。)
5 不定式作表語
不定式可放在be動詞后面,形成表語。例如:

3) 表原因 I'm glad to see you.
The chair looks rather hard, but in fact it is very comfortable to ___.
A. sit B. sit on C. be seat D. be sat on
答案:B. 如果不定式為不及物動詞,其后應有必要的介詞。當動詞與介詞連用時,常位于"形容詞+動詞不定式"結(jié)構(gòu)的末尾。
8 用作介詞的to
to 有兩種用法: 一為不定式+動詞原形; 一為介詞+名詞/動名詞, to 在下面的用法中是第二種,即to+ 名詞/動名詞:

5) The patient was warned ___ oily food after the operation.
A. to eat no B. eating not C. not to eat
D. not eating

1. 分詞的定義 動詞的-ed分詞即過去分詞,是由動詞的過去分詞構(gòu)成,一般只有一種形式。 2. 過去分詞的語法作用:
過去分詞一方面具有動詞的性質(zhì),另一方面也相當于一個形容詞或副詞,在句中可以作表語、定語、狀語和補足語。
1) 過去分詞作表語,主要表示主語的心理感覺或所處的狀態(tài)。如:
Don’t touch the glass because it is broken. 不要碰那個杯子,它是壞的。
He is quite pleased with the design of the dress. 她很喜歡那禮服的式樣。
2) 過去分詞做定語:
單個的過去分詞作定語一般放在名詞的前面,相當于一個定語從句。如:
The excited people rushed into the building. 激動的人們奔進了大樓。
We need more qualified teachers. 我們需要更多合格的教師。
過去分詞短語作定語通常放在被修飾的詞后面,相當于一個定語從句。如:
Is there anything planned for tomorrow? 明天有什么活動嗎?
The suggestion made by the foreign expert was adopted by the manager. 外國專家提出來的建議被經(jīng)理采納了。
過去分詞作定語也可用作非限制性定語,前后用逗號隔開。如:
The books, written by Lu Xun, are popular with many Chinese people.這些書是魯迅寫的,受到了許多中國人民的喜愛。
The meeting, attended by one thousand students, was a success. 這次會議獲得很大的成功,共有一千個學生出席了。
3) 過去分詞做狀語:
過去分詞和-ing分詞作狀語一樣,也可以表示時間、原因、條件、讓步、方式或伴隨情況等。
、俦頃r間,相當于一個時間狀語從句,有時過去分詞前可加連詞when或while來強調(diào)時間概念。如:
Seen from the top of the hill, the city looked like a big garden. 從山頂上看,這個城市就像一個大花園。
Accepted by the Party, he decided to devote his life to the cause of the Party.
入黨以后,他決定獻身于黨的事業(yè)。
②表原因,相當于一個原因狀語從句。如:
Deeply moved by the story, the excited people stopped quarrelling with each other.
激動的人們被那個故事深深地感動了,停止了爭吵。
Encouraged by the speech, the young people made up their minds to take up the struggle.
受到了講演的鼓舞,年輕人決定起來從事斗爭。
③表條件,相當于一個條件狀語從句,有時過去分詞前可用if等詞。如:
Given another chance, he will do better.再給他一次機會,他會做得更好。
Compared with your brother, you should make greater efforts to study English.
和你哥哥相比,你應該更加努力學習英語。
If heated, water can be turned into steam. 水如果被加熱,會變成水蒸氣。
、鼙碜尣剑喈斢谝粋though/although引導的讓步狀語從句。如:

盡管已經(jīng)跑得筋疲力盡,他們還是繼續(xù)追趕著那個強盜。
Laughed at by many people, he continued his study. 盡管被許多人嘲笑,他還是繼續(xù)他的研究。

The old man went into the room, supported by his wife.那個老人在他的妻子的攙扶下走進了房間。
Seated at the table, my father and I were talking about my job. 我和父親坐在桌子旁邊討論著我的工作問題。
4) 過去分詞作補足語:
過去分詞可以在see, hear, notice, watch, find, get, have, feel, make, leave, keep等詞后與一名詞或代詞構(gòu)成復合賓語,用作賓語補語。如:
When will you go to the hospital and have your tooth examined? 你什么時候去醫(yī)院檢查你的牙齒?
When you are making a speech, you should speak louder to make yourself heard.
當你在作報告時,你應該講響一點使自己被人聽清。
當這類句子變成被動語態(tài)時,過去分詞用作主語補語。如:
One of the glasses was found broken. 有人發(fā)現(xiàn)其中一個杯子破了。
They should be kept informed of the situation there. 應該讓他們知道那兒的形勢。
二、特別提醒
1. 過去分詞作狀語時,它的邏輯主語一般必須和句子的主語相一致。如:
When asked why he came here, the boy kept silent.當那個男孩被問到為何來這里時,他沉默不語。
Born and brought up in the countryside, he was interested in biology.
由于在農(nóng)村出生并長大,他對生物很感興趣。
如果過去分詞的邏輯主語和句子主語不一致,必須使用過去分詞的獨立主格結(jié)構(gòu)。
2. 動詞have后所接的三種賓語補語:
have somebody/something do something 不定式作補語必須省去to, 不定式動作由賓語發(fā)出,表示一次性的動作。如:
I had the workers do the job for me. 我讓工人們替我完成了工作。
Jim often has his father help him with his homework. 吉姆經(jīng)常讓他的父親幫助做家庭作業(yè)。
have somebody /something doing something -ing分詞作補語,分詞動作也由賓語發(fā)出,強調(diào)動作的延續(xù)或正在進行。如:
They had the tractor working all the time. 他們讓拖拉機一直工作著。
We won’t have the child talking to his mother like that. 我們不能讓那個孩子那樣對他的媽媽說話。
have somebody/something done 過去分詞作補語,賓語和補足語之間有邏輯上的被動關(guān)系,通常有兩種情況:
、僦髡Z讓別人做某事,強調(diào)主語的意志。如:
He had his hair cut yesterday. 他昨天理發(fā)了。
Later on the center had a great many new trees planted.后來,這個中心讓人種了很多樹。
②主語遭到某種不幸或陷入惡劣的環(huán)境,說明賓語的一種無意識的被動行為。如:
He had his leg broken in the match last month.他在上星期的比賽中摔斷了腿。
He had one eye lost in the war. 在戰(zhàn)爭中,他失去了一只眼睛。
3. 非謂語動詞的被動式作定語的三種形式:
the bridge to be built 將要建造的橋 (表示將來的動作)
the bridge being built 正在建造的橋 (表示正在進行的動作)
the bridge built 造好的橋 (表示完成的動作)
4. 過去分詞和–ing分詞作表語的區(qū)別:
過去分詞作表語通常表示主語所處的狀態(tài)或感受,而-ing分詞作表語多表示主語所具有的特征,如:
Hearing the news, we felt very surprised. 聽到那個消息,我們感到很驚訝
The news is very surprising. 這個消息很令人驚訝。
They were frightened to hear the frightening sound. 他們聽到那可怕的聲音很害怕。
At the sight of the moving scene, all the people present were moved to tears.
看到這么動人的情景,所有在場的人都感動得流下了眼淚。
英語中這樣的分詞還有很多,如:amusing, amused; encouraging, encouraged; disappointing, disappointed; exciting, excited; puzzling, puzzled; satisfying, satisfied; worrying, worried; tiring, tired; pleasing, pleased; interesting, interested; astonishing, astonished等。
5. 過去分詞和–ing分詞作定語的區(qū)別:
過去分詞作定語和-ing分詞作定語有一定的區(qū)別。試比較下面幾組短語:
boiled water開水 boiling water正沸騰的水
developed countries發(fā)展的國家 developing countries發(fā)展中國家
fallen leaves落葉 falling leaves 正在飄落的葉子
changed condition改變了的情況 changing condition變化著的情況
由此可見,過去分詞作定語通常表示完成的或被動的動作;而-ing分詞作定語可以表示正在進行的主動的動作。
